Export to mp3/wav is broken.
Sometimes I get silence over my whole audio file. And the funny thing is that previously in the same project the export overwrote the 10-15 seconds with silence, then after working with the project for a while it was 2-3 minutes. And now it’s silence over complete project (around 6 mins). This is for both Wav and Mp3. So when I keep adding stuff, the amount of overwritten silence increases. I have gotten it to work sometimes by luck, and sometimes maybe by deleting all the extra bars (which were meant for sketching and the safekeeping) at the end of the project.
And yes the playback works when exporting. Well, not always, there is a bug too and sometime for some reason the playback goes totally silent even though the instruments have all loaded properly and can be played in Halion Sonic SE interface. This is usually when Dorico crashes intermittently crashes loading the project (see a bug there too) and then you load it again you can’t hear anything. You can fix this by restarting and loading the project.
Export to audio (when it works) doesn’t care about the tempo markings at all and it exports to around 120 bpm. Actually I got it to work only once. When I changed tempo to presto (to 172 from 132). Then I changed it back to 144 bpm (did nothing else) and guess what…export to audio added around 20 sec more silence to the beginning.
I have used better-working betas than this “release” version.
